fast efi problem

i only have 2 splices, main power and ground to battey because its in the trunk. ive rerouted wires. the highest number ive seen on the rms is 08.
if the computer wont learn and randomly kills the engine, and i mean ''kills'' as if the ignition is cut, wouldn't that point towards a problem with the ecu ?
with all the wiring and adjustments ive made there is absolutley no change.
